ABSTRACT
This book is testament to the renewed interest in environmental influences on human health. In contrast with the nineteenth century, ill health now stems, at least in the developed world, from chronic rather than infectious diseases. And, although obesity has received the most attention in environmental research, there is now an understanding that where we live and work affects not just our physical health but also our mental health, and our general well-being (Jackson et al. 2013). Depression has been ranked among the ten leading contributors to the global burden of disease and is projected to be among the top three by 2020. Mental illness in general plays a large part in loss of productivity through days off work. So it is vital that it is addressed.
